How to Replace a New Line in SQL

To replace a new line in SQL, use the REPLACE function.

The REPLACE function is used to replace a specified string with another string. It takes three arguments:

• The string to be replaced
• The string to replace it with
• The string in which the replacement should be made

For example, if you wanted to replace all new lines in a string with a space, you would use the following query:

SELECT REPLACE(string, '\n', ' ') FROM table_name;

Examples

Let's look at a few examples of how this function can be used. Suppose you have a table called users with the following data:

If you wanted to replace all new lines in the address column with a space, you would use the following query:

SELECT REPLACE(address, '\n', ' ') FROM users;

This query would return the following result:

name      address
------------------------
John      123 Main St. 456 Elm St. 789 Oak St.
Jane      123 Main St. 456 Elm St. 789 Oak St.
John      123 Main St. 456 Elm St. 789 Oak St.
Bob       123 Main St. 456 Elm St. 789 Oak St.

Additional Info

The REPLACE function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database.
